Assessment of antibiotic resistance in bacteriophage-insensitive Klebsiella pneumoniae.

abstract：:Upon oxygen shift-down, Mycobacterium tuberculosis complex bacteria can induce a genetic program characterized by halted duplication, which is called Non-replicating persistence (NRP). During this phase, at least 48 genes, collectively named Dormancy survival regulator (DosR) regulon, are important for the long-term s...
